DragonPlate carbon fiber C70-40 Airex foam core is a unique closed cell, cross-linked polymer foam core. This is a lightweight structural foam that has good impact strength. While great for high strength applications which require a low panel weight, this is a carbon fiber foam core laminate that can resist crushing forces and supply an adequate mounting surface. The lay-up design is quasi-isotropic, consisting of three layers of carbon fiber on each side of a 1" Airex foam core center. Available in gloss, matte or texture on one side and texture on other side for bonding to other surfaces. For foam specifications, please refer to the official Airex Data Sheet.
